האינסטלטור אמר שהברז הישן לא טוב וצריך להחליף אותו.

שה means that in this kind of sentence.

So:

• האינסטלטור אמר = the plumber said
• שהברז הישן לא טוב = that the old faucet isn’t good

It introduces a subordinate clause, just like English that in He said that....

In everyday Hebrew, ש or שה is very common for that. In more formal Hebrew, you may also see כי, but ש/שה is extremely normal in speech.

Because in Hebrew, when a noun is definite, its adjective usually becomes definite too.

• ברז ישן = an old faucet
• הברז הישן = the old faucet

So:

• הברז = the faucet
• הישן = the old

This is a very important Hebrew pattern:

• ספר טוב = a good book
• הספר הטוב = the good book

Unlike English, Hebrew typically marks definiteness on both the noun and the adjective.

Hebrew very often uses לא טוב literally not good where English might say bad, no good, or not okay.

So:

• הברז הישן לא טוב literally = the old faucet is not good
• natural English meaning = the old faucet is bad / no good

This is very normal, especially in speech. It can sound a little less dramatic or less formal than using a stronger adjective like גרוע.

Here צריך means it is necessary or one needs to.

So:

• צריך להחליף אותו literally = it is necessary to replace it
• natural English = it needs to be replaced or you need to replace it

A key point: there is no explicit subject here. Hebrew often uses צריך + infinitive in an impersonal way, especially in spoken language.

So this does not necessarily mean:

• he needs to replace it

Even though צריך is grammatically masculine singular, in this kind of sentence it often works like an impersonal need to.

Because Hebrew often leaves that kind of subject unstated when the meaning is general or impersonal.

English often says:

• It needs to be replaced
• You need to replace it
• It is necessary to replace it

Hebrew can express the same idea more compactly:

• צריך להחליף אותו

This is a very common difference between English and Hebrew. Hebrew often sounds less explicit about the subject when the context makes it clear.

להחליף is the infinitive form of the verb to replace.

The ל at the beginning often corresponds to English to before a verb:

• להחליף = to replace
• ללכת = to go
• לעשות = to do / to make

So:

• צריך להחליף אותו = need to replace it

This is a very common structure:

• צריך לעבוד = need to work
• רוצה לאכול = want to eat
• אפשר לראות = it is possible to see

אותו means him or it in the masculine singular form. Here it refers to הברז.

Since ברז is a masculine noun, the object pronoun must also be masculine:

• ברז = masculine
• אותו = it/him masculine singular

So:

• להחליף אותו = to replace it

If the noun were feminine, Hebrew would use אותה instead.

Example:

• הדלת ישנה וצריך להחליף אותה = The door is old and it needs to be replaced

Mostly from usage. Hebrew nouns do not always show gender clearly from their form.

In this sentence, you can tell ברז is masculine because of the words agreeing with it:

• הישן = masculine singular adjective
• אותו = masculine singular object pronoun

If ברז were feminine, you would expect forms like:

• הישנה
• אותה

So the agreement gives you the answer.

In theory, a learner might wonder that, but in this sentence the natural reading is impersonal:

• והוא צריך להחליף אותו would clearly mean and he needs to replace it
• וצריך להחליף אותו by itself usually means and it needs to be replaced / and one should replace it

So the actual sentence is more general and less tied to a specific subject.

Because the speaker is talking about the faucet’s condition, the meaning is:

• The plumber said the old faucet isn’t good and needs to be replaced

not:

• The plumber said the old faucet isn’t good and he needs to replace it

Even if English translation can vary, the Hebrew strongly suggests an impersonal needs replacing idea.

ו means and.

It connects two things the plumber said about the faucet:

1. הברז הישן לא טוב = the old faucet isn’t good
2. צריך להחליף אותו = it needs to be replaced

So together:

• שהברז הישן לא טוב וצריך להחליף אותו
• that the old faucet isn’t good and needs to be replaced

This is a very common use of ו to join clauses.

No, it is a borrowed word, from installer/plumber-type European roots. But in modern Hebrew it is a completely normal everyday word meaning plumber.

The ה at the beginning is just the Hebrew definite article the:

• אינסטלטור = a plumber
• האינסטלטור = the plumber

So even borrowed words behave like regular Hebrew nouns in the sentence.

The structure is:

• האינסטלטור = subject
• אמר = verb
• ש... = content clause introduced by that

So literally:

• The plumber said that the old faucet is not good and needs replacement

A helpful breakdown:

• האינסטלטור — the plumber
• אמר — said
• שהברז הישן — that the old faucet
• לא טוב — is not good
• וצריך להחליף אותו — and needs to be replaced / and one needs to replace it

This kind of sentence structure is very common in Hebrew: X said/thought/knew that...

Yes, this sounds natural and everyday.

Especially colloquial features include:

• שה for that
• לא טוב for not good / no good
• impersonal צריך להחליף אותו for it needs to be replaced

A speaker might also say similar versions such as:

• האינסטלטור אמר שהברז הישן לא בסדר וצריך להחליף אותו
• האינסטלטור אמר שהברז הישן מקולקל וצריך להחליף אותו

But your sentence is completely normal and natural.
